To all' whom it may concern: Be it known that I, CALvlN F. Cnmsf, '.rornnn, a citizen of the United States,` 11esiding at Asheville, in the county ofrBun-` 5 Conil i and b'tltey of North Carolina7 have `invented a new and useful Computing-r Scale, of which the following is a specification. i u ,v This invention relates to coniputing'eezilegV its object' being to provide a simple and com.:-

pact structure of this type which will iinp:

dicate accurately the number of.;,-ponnds,` the prices per pound, and the price for `the total nuniber of pounds being weighed. y

AnotherV object is to provide*improvedi` means for transinittilng niotion from; thevv pan to the computing mechanism.y

The peripheral portions-ot the cylinders 3l and 32 are provided with longitudinal and annular lines subdividing said surface into spaces. The series of spaces 'extending around one end of the cylinder 3l, and Awhich has beenindicated at 34, contains. two sets of numerals ranging from zero to any de` sired number, the numerals of one series being disposed diametrically opposite the numerals of the other series so that When one numeral appears at a predetermined point in the slot extension 26, a similar numeral Will appear Within the opening 27. The other spaces on the peripheries of cylinders 31 and 32 contain numerals indicating the price asked for, the number of pounds indicated by the numerals 34, and any of the prices per pound indicated in the spaces 28. For example, should the numeral l appear opposite the index marks 25 adjacent to the openings 26 and 27 the numeral appearing through slot 24 above the numeral 25 will be 50, which is the price to be asked for pound. Y i

The means for connecting the shaft 30 to the ends ofthe casing' 20 has been shown specifically iILF ig. 4. By referring to this ligure it. will be seen that 'the end of the shaft is tapered, asat 36 and bears Within a conical recessl37 formed in one end of an adjusting screw 38, said screw, being mount ed in a bracket 39'carried b a spider 40 or the like` seeured Within4 t e housing 20L mechahism4 can be concealed y means of a cap 41 removably' mounted Withinthe -end .of the casing.

What is claimed is l.v Computing scales including a casing' having slots one of which has a downward extension, adjustable bearing members mounted within the end' portions or' the casing, a shaft mounted at its ends Within said bearing members, caps of the casing for concealing the l bearing members, spaced cylinders carried by the shaft and having numerals thereon indicating the prices of one o r more' pounds at different prices per pound, one of said cylinders having dlametrically opposed series of pound designatingfnumerals, the numerals 0f one series being visible successively with.-
